摘　　要：外海大型原油码头工程一般位于浪大、水深的开敞水域,且码头多为蝶形布置。墩式结构选型多而复杂,海上施工难度大。以海南洋浦30万吨级原油码头及配套储运设施工程为例,介绍了黏性土地基上的外海大型原油码头水工建筑物的结构方案选型,从结构设计、耐久性设计、施工工艺、后期维护和全寿命期成本方面研究高桩墩台结构和重力式沉箱墩结构两种水工结构的全寿命期方案。The offshore large crude oil terminal project is generally located in the open sea with large waves and water depth,and the wharf is mostly butterfly. The pier foundation type is multiple selection and complicated,and the construction is difficult. Taking Yangpu 300,000 ton crude oil terminal and transportation facilities project in Hainan Province as an example,this paper introduces the structure selection of offshore large-scale crude oil terminal＇s marine structure on cohesive soil.It also demonstrates the lifecycle proposal for the high-pile pier foundation and caisson pier foundation in aspects of structure design,durability design,construction technology,later maintenance and cost.
